Pancreaticoduodenectomy can be indicated for elderly patients: risk prediction using the estimation of physiologic ability and surgical stress (E‐PASS) system

BACKGROUND Pancreaticobiliary malignant diseases are primarily treated by surgical resection. However, the surgical indications for elderly patients, especially for pancreaticoduodenectomy (PD), must be carefully considered due to patient compliance. Whether PD can contribute to better prognoses in elderly patients remains unclear. Therefore, we aimed to evaluate the complications, compliance, and survival of elderly and non-elderly patients who underwent PD in our department. METHODS We retrospectively analyzed 282 patients who underwent PD from 2000 to 2017 and divided them into non-elderly (aged ≤ 79 years, n = 238) and elderly (aged ≥ 80 years, n = 44) groups. The estimation of physiologic ability and surgical stress (E-PASS) system was used to evaluate morbidity and mortality using preoperative risk score (PRS), surgical stress score (SSS), and comprehensive risk score (CRS). RESULTS Preoperative risk score was higher in the elderly group than in the non-elderly group, although SSS and CRS were similar. No significant differences were detected in the occurrence of postoperative complications. In the elderly group, CRS was higher in patients with complications than in those without. Long-term outcomes evaluated by overall and disease-specific survival were not significantly different. CONCLUSIONS In the elderly patients, E-PASS especially CRS can predict the occurrence of complications. The safety and prognoses of elderly patients after PD are comparable with those of non-elderly patients.
